Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-demand radio transmitting / receiving apparatus and method for a vehicle user, and more particularly, to an on-demand radio transmitting / receiving apparatus and method for a car user.
The present invention relates to an on-demand radio transmitting / receiving apparatus and method for a vehicle user using commercial (CM) broadcasting.

[0002]

2. Description of the Related Art At present, car navigation systems (car navigation systems) used in cars are becoming widespread. As an advanced form of this, there is a car navigation system having a communication function. Information such as restaurants and play spots is loaded into a car navigation system via a mobile phone or car phone. Store information is C
Although such information is also included in D and DVD software, such information is fluid, and the advantage of a car navigation system having a communication function is that it can correspond to the latest information through communication.

[0003] Examples of the "information service specialized in providing information for car drivers" include Toyota-related Monet, Nissan-related compass links, Honda Motor-related internavi, and Mercedes-Benz-related There are five types of mobile links in which ITGS and car navigation makers participate. These are premised on two-way communication between the service side and the vehicle side.

[0004] Apart from these, there is a "VICS information service". In the VICS, traffic congestion and regulations, vacancy information of parking lots, and the like can be taken into the navigation screen.
VICS uses two types of beacons, a light and a radio wave, transmitted from a beacon along a highway, and a wide area FM radio wave. This is one way from the service side to the vehicle side.

[0005] In the field of the Internet, there is a so-called PUSH technology which is widely used. For example, Pointcast (refer to www.point
tcast. com), the pointcast mechanism is such that when the user registers the type of necessary information in advance, the user-side PC sends a WWW server at an appropriate timing (eg, every hour, every day, etc.). , The latest information on the WWW server is automatically acquired, and the latest information is presented on the user PC. From the viewpoint of the user, information related to the desired information specified by the user can be automatically and successively seen.

[0006] Japanese Unexamined Patent Application Publication No. 7-336256 discloses a method.
The described technology is a technology of an automobile traffic information selection device that can select a traffic information program based on the latest broadcast schedule of a broadcast station that can be received in each region.

[0007]

The above-mentioned "information service specialized in providing information for automobile drivers" has the following problems. -Users need to pay information service fees. -Users need to pay for mobile phone charges. -Although bidirectional communication is possible, while providing high functionality, it requires various inputs to the user side, and if the user is a driver, there is a possibility that the driving operation will be hindered.・ The current communication speed is 96 because it is via a digital mobile phone.
There is only 00bps.

[0008] The above-mentioned "VICS information service" has the following problems. -Since VICS is broadcast rather than communication, it does not provide information according to the specific situation of each user. -VICS of FM radio provides only wide area information, and beacons provide more detailed information. To get more information, you need to purchase a beacon receiver. However, beacon transmitters are installed only along arterial roads. -The user will pay the information service usage fee substantially by purchasing a special beacon receiver.・ Store information is not provided for public information services.

A first problem of the technique described in the above-mentioned Japanese Patent Application Laid-Open No. 7-336256 is that two systems of a pager and a broadcast are required. The second problem is that since the broadcast is not repeated, there is a high possibility that information is overlooked (for example, when a car enters a tunnel or the like, it is difficult to receive radio waves and obtain information. May be). A third problem is that only traffic information can be obtained.

In order to realize an ideal service providing form for a driver, the following two conditions must be satisfied.

First condition: adaptation information for the user.

It is necessary to provide only information according to the situation and preferences of each user. Since the main user is driving, the user interface is simple, and if possible, it is convenient to operate without any operation and to provide information in a flowing manner. This is a one-way interface like a radio. For example, "This is where McDonald's is."
Drivers will be radio like "Fireworks display will start in one hour in our city", "From today (or from tomorrow), there will be an exhibition at Horyu-ji Temple at the Y Art Museum in the city next to X". If only the information necessary for the current location, time and situation is selected and flown on its own, the driver does not need to operate anything by himself.

[0013] At present, there is no information providing service adapted to individuals as described above for car navigation systems, but even if provided, it requires a two-way communication function, which in particular increases the cost of the user. I will.

Second condition: User's burden is unnecessary (or minimum) and provider's expense is satisfactory.

The user does not want to pay the usage fee. Assuming this, a device such as a mobile phone cannot be used (unless the information providing service bears the communication fee). For that purpose, a mechanism that has advantages for both the driver side and the information providing side is necessary. At present, TV viewing of commercial broadcasting is free for viewers, because the broadcasting fee is paid by the CM sponsor. This is because the sponsor is aware of the effect of paying the fee. From the viewpoint of the viewer, in commercial broadcasting, not only the CM film is played, but also a program such as a drama that is attractive to the viewer and a CM film accompanying the program.

Thus, the viewer naturally watches the CM film. If only CM films are used, busy viewers will not watch commercial programs. Similarly, there is a need for a mechanism that the CM sponsor can afford and wants to bear, and that the viewer wants to keep listening (including the burden fee).
None of the ideal requirements for the user can be realized with the current services.

In order to satisfy the first condition, the user must register the type of information necessary for the user, and the provider needs to provide only the information required by the user to the user. . If only the information necessary for the user is provided, the user does not need to say “I want this” on demand, and the user interface is also simplified.

The above-described Pointcast is a technique for satisfying the first condition. This looks like a TV at first glance, but TV is intended for an unspecified number of viewers, whereas Pointcast,
Only the type of information specified by the user is presented. In other words, it is a personalized broadcast. But,
The mechanism of operation uses communication, and the user's PC
Accesses the WWW server, so using it in a car using a mobile phone naturally costs money for the mobile phone. In other words, it is completely different from broadcasting in terms of realization.

In order to satisfy the second condition, there is no satisfactory solution for both the user and the information providing side as long as the current communication infrastructure is used. Even the US market, which is cheaper than Japan,
Mobile phones currently cost $ 30 per month for up to 100 hours,
Is a typical service. In Japan it costs even more. Even if this amount is paid, the information that the user wants to obtain is limited. Or, even if the information provider bears the burden, it is hard to find the merit of providing the information to the individual driver by paying this amount.

Therefore, it is possible to reduce costs by using a broadcasting infrastructure instead of using a communication infrastructure, and to provide a service that can be realized at present only with the communication infrastructure.

The object of the present invention can be realized only by a communication infrastructure for a vehicle driver whose time, place, and type of necessary contents change every moment by using a broadcasting infrastructure (without using a pager). (I.e., by repeatedly broadcasting a set of commercial (CM) programs, the receiving side pre-fetches and saves the information, and the information is retrieved and played back when necessary. Without having to do expensive processing), the information will be broadcast to the general public as a broadcast from the provider,
By selecting it according to the TPO (time, place, type) on the receiving side, a broadcast customized for an individual is realized.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the principle of the present invention will be described in detail with reference to the drawings. FIG. 5 is an explanatory diagram showing the principle of the present invention. Referring to FIG. 5, the present invention incorporates location, time, and content (for example, location: area X direction, time: unrelated to time zone, content: content type C1) in satellite digital broadcasting or terrestrial digital broadcasting. A set of multiple CM programs is repeatedly broadcast simultaneously.
For example, if the place is a freeway area where a corn field extends continuously like the Midwest of the United States, the number of CM providers is small, so a considerably large area is set as one area. In addition, there are different restaurants, shopping malls, convenience stores, etc. at each exit of the freeway around Silicon Valley, and they may put out commercials,
In this case, it is desirable to set a fairly small area as an area (for example, about Silicon Valley).

In the on-vehicle device, the user's preference information is registered in advance and held. In addition to the content of the preference information, the current time is obtained from the clock and the current location is obtained from the GPS. Using this information, a commercial broadcasted simultaneously
From the program, only information that matches the content of the favorite information, the current time, and the current location is selected and presented to the user.

By doing so, "In the vicinity,
There is McDonald's "," In one hour, the fireworks festival will start in our city "," From today (or from tomorrow)
The Horyuji Exhibition will be held at the Y Art Museum in the city next to X ".

Also, if coupon information is added to this information, it is possible to measure the effect of flowing these CMs. For example, "There is McDonald's near the next exit. If you heard this program,
Please say BC and the counter. "50 cents will be discounted." By measuring how many of the customers who visit the store are ABC, the effect of this CM can be understood.

Next, the principle of the CM program will be described with reference to the drawings. FIG. 6 is an explanatory diagram showing the contents of the CM program. The contents of CM programs broadcasted by digital broadcasting are, for example, XML (Extensible Mark), which has recently become popular in the WWW world.
up Language). XML
Is a language that can express the contents of a document by a set of pairs of attribute tags and their attribute values (refer to the World Wide Web Consortium homepage, “Extensible Markup Language, 1.0”, http: // www.w3.org/
TR / PR-xml-971208).

In addition, XML is a World Wide Web Consortium (refer to:
World Wide Web Consortium homepage,
http://www.w3.org), the specification of which was proposed in December 1997.

Referring to FIG. 6, the CM program is X
It is described in ML. In XML, the DTD file (CM
-Program. In dtd), the format of the document is defined. The format of CM-program is <time>, <time>
It is composed of fields of <place>, <type>, and <content>. The contents of each CM program are stored in separate XML files. In FIG. 6, the information of the fireworks display is included in the XML file (CM-program.xml).
gram. It is described according to the format specified by dtd.

CM-program. xml <contents>
<Voice SRC = "voice.wav"> is a voice file "voic" in which a description of the fireworks display is recorded.
e. wav ", and this file is
-Program. xml is broadcast.

For example, if the user wants to obtain the “festival” information, he or she registers it in advance as a favorite, and
If you go to City A between 17:00 and 21:00 on August 7, 2009,
At that time, this information is presented to the driver. It is easy to match the time information in the CM program with the current time.

The location information in the CM program is longitude and latitude information in FIG.
, It is easy to match. CM
Matching is easy if the content type information in the program is defined in advance by defining a finite number of types and selecting from among them.

Next, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
It is a block diagram showing an embodiment. Referring to FIG. 1, a first embodiment of the present invention is a CM broadcasting device 11 installed in a broadcasting station for digital terrestrial broadcasting and installed in an artificial satellite for digital satellite broadcasting, and a CM program 17. , A preference storage 12 installed in an automobile, a time storage 13, a location storage 14, a CM program selector 15, a regenerator 16, and an address / longitude / latitude correspondence unit 18.

The CM program 17 is described in XML, and its fields include <time>, <location>, <type>, and <content>. <Time> describes the time when this CM program is valid. <Location> describes a location related to this CM program. The <type> describes the content classification code (for example, restaurant, convenience store, shopping mall, home center, hospital, amusement park, museum, etc.) of this CM program.

For example, when a restaurant serves as a sponsor and wants to advertise a special sale at lunchtime, <time> describes the time zone of lunchtime, and <location> describes the address of the restaurant. Is described, and <type> describes that it is “restaurant classification”. For example, in <contents>, a description indicating an audio file of the content of the special sale is stored.

If this restaurant wants to broadcast only ordinary restaurant information without performing a special sale at a specific lunch time, the description "anytime" is stored in <time>. In <time>, a date level may be described instead of time level information. For example, when a special exhibition is held at a certain museum, "from what month to what day" is described.

Next, the operation of the first embodiment of the present invention will be described. FIG. 7 is an explanatory diagram illustrating the operation of the first exemplary embodiment of the present invention. Referring to FIG. 7, the CM broadcasting device 11 collectively broadcasts a plurality of CM programs A, CM programs B, and CM programs, and periodically and repeatedly broadcasts them.

The preference storage 12 stores the type of information desired by the user. This is the same type as the value stored in <type> of the CM program 17. The time storage 13 automatically stores the current time read from a clock (not shown). This is updated, for example, every minute.

The location storage 14 has a GPS (see FIG. 5).
Is stored in the form of longitude and latitude. This is also updated, for example, every minute. When given an address, the address / longitude / latitude correspondence unit 18 converts the address into longitude / latitude information. As a simple implementation,
If the target is all over Japan, an item is set for each street level of municipalities throughout Japan, the corresponding longitude and latitude information is stored in a table, and the table is searched using the address data at the street level as a key to search the table. Can be converted to latitude information.

The CM program selector 15 receives the unit of the CM program 17 broadcasted from the CM broadcasting equipment 11 and describes the description of <type>, <time>, and <place> in the preference storage 12 and the time storage. 13. The value stored in the location storage unit 14 is compared, and only the CM program that matches is output.
Pass to.

The reproducing device 16 receives the received CM program 1
Take out the value of the 7 <content> field and play it back.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 shows a second embodiment of the present invention.
It is a block diagram showing an embodiment. The second embodiment of the present invention is obtained by adding functions to the first embodiment of the present invention. That is, the CM program is combined with the service program. This adopts the technique adopted by commercial TV. A service program such as a classical music channel and a popular song channel is provided to the user free of charge, for example, a commercial program is played for 5 minutes every 30 minutes.

Referring to FIG. 2, a second embodiment of the present invention is a CM broadcasting apparatus 11 installed in a broadcasting station in the case of terrestrial digital broadcasting and in an artificial satellite in the case of satellite digital broadcasting, CM program 17, service broadcasting equipment 21, CM-to-service allocation degree designator 22, service program 23, and preference storage 12 installed in a car
, A time storage unit 13, a location storage unit 14, a CM program selector 15, a reproducing unit 16, an address / longitude / latitude correspondence unit 18, a broadcast mixer 24, and a CM program storage unit 2.
5 and a timer 26.

The CM broadcast equipment 11 to the address / longitude / latitude correspondence unit 18 are the same as those in the first embodiment of the present invention (see FIG. 1). However, the output of the CM program selector 15 is not sent directly to the reproducer 16 but is once stored in the CM program storage 25.

Next, the operation of the second embodiment of the present invention will be described. 8 and 9 are explanatory diagrams showing the operation of the second embodiment of the present invention. In the second embodiment of the present invention, the CM program 17 is combined with the service program 23 as described above. Service broadcasting equipment 2
1 broadcasts digital data similarly to the CM broadcasting device 11. For example, if the service program 23 is a service for distributing music dedicated to classical music, the service program 23 is music dedicated to classical music. That is, the service broadcast equipment 21
Keeps playing classical music.

The service program 23 does not need to have special field information unlike the CM program 17. Of course, the type may be stored in the service program 23, and the preference of the user may be reflected on the type.

Referring to FIG. 8, service broadcast equipment 21
Does not periodically repeat a plurality of service programs as in the CM broadcasting device 11. That is, another program is broadcast one after another like a normal radio program.

The CM-to-service allocation degree designator 22 stores the distribution ratio of the service program 23 and the CM program 17. For example, if the service program is distributed for 50 minutes and the CM program for 10 minutes in one hour, a value of “5: 1” is recorded.

In accordance with this ratio, as shown in FIG. 9, the CM is delivered with a CM delivery blank time interval between service programs. At the boundary between this service program and the blank time zone, a “start tag” expressing the boundary and a “blank time length” indicating the length of the blank time zone are inserted.

The broadcast mixer 24 receives the service program 23 normally transmitted from the service broadcasting device 21 and passes it to the reproducer 16 as it is. The regenerator 16
Play it as it is. When the broadcast mixer 24 finds the “start tag” indicating the CM delivery blank time zone from the service broadcasting device 21, it sets the blank time length to the timer 26 and starts the timer 26. Then, the CM program 17 stored in the CM program storage 25 is taken out and passed to the reproducing device 16.

The timer 26 counts down and informs the broadcast mixer 24 when the blank time ends.
The broadcast mixer 24 then stops taking out the CM program 17 from the CM program storage 25 and restarts the reception of the service program 23 of the service broadcasting device 21 and the delivery to the reproducer 16 again.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings. FIG. 3 shows a third embodiment of the present invention.
It is a block diagram showing an embodiment. The third embodiment of the present invention is obtained by adding functions to the first embodiment of the present invention.

Referring to FIG. 3, a third embodiment of the present invention is a CM broadcasting device 11 installed in a broadcasting station for digital terrestrial broadcasting and installed in an artificial satellite for digital satellite broadcasting. Second CM broadcast equipment 31, CM program 17, preference store 12 installed in car, time store 13, place store 14, CM program selector 15, reproducer 16, address / longitude A latitude correspondence device 18;
And a CM broadcast device selector 32.

The value of the location storage 14 is passed not only to the CM program selector 15 but also to the CM broadcast equipment selector 32. CM transmitted by CM broadcasting equipment 11
The program is not passed directly to the CM program selector 15 but received by the CM broadcast device selector 32.

The second CM broadcasting device 31 is the CM broadcasting device 1
The configuration is the same as that of No. 1 except that the area in charge of each is different. Two or more CM broadcasting devices can be installed. In an area where cities are dense, such as San Francisco and the Kanto region, a separate CM broadcasting device may be prepared as a separate channel for each city, ward, or more detailed unit.

Next, the operation of the third embodiment of the present invention will be described. The CM broadcast device selector 32 is used to select the location information and the CM broadcast device 11 and the second CM broadcast device 31 to be selected.
Of the CM broadcast equipment 1 by receiving the current location information indicated by the location storage 14 and selecting the channel to be selected.
1 or the second CM broadcasting equipment 31, and receives the CM program 17 of the selected channel,
Transfer to the M program selector 15. The CM program selector 15 compares the <type>, <time>, and <location> described in the CM program 17 with the values in the preference storage 12, the time storage 13, and the location storage 14, and matches the CM. Only the program is output and passed to the reproducer 16. Regenerator 16
Retrieves the value of the <content> field of the passed CM program 17 and reproduces it.

Thus, the CM program 17 can be provided on a plurality of channels. If there are many providers of the CM program 17 in an urban area, the C
